Delta baggage allowance and fees
Delta is more generous than most U.S. airlines on carry-ons, and its checked-bag fees are worth knowing before you pack.
Every fare, including Basic Economy, includes one free carry-on bag plus a personal item. The carry-on can be up to 22 by 14 by 9 inches including wheels and handles, with no weight limit on domestic flights. On smaller regional (Delta Connection) jets, only the personal item comes onboard and the carry-on is gate-checked for free.
On domestic flights, the first checked bag is $45 and the second is $55, each way. Bags must stay within 50 pounds (23 kg) and 62 linear inches. Medallion members, Delta SkyMiles American Express cardholders, active military, and premium-cabin flyers get at least one free checked bag.
A bag from 51 to 100 pounds adds $100, and one measuring 63 to 80 linear inches adds $200. Anything over 100 pounds or 80 inches won't be accepted.
Delta cabin classes
Delta One
Basic Basic Economy (Delta Main Basic)
The lowest fare. You still get the free carry-on and personal item, but your seat is assigned at check-in, the ticket earns no SkyMiles, it can't be changed after the 24-hour window, and it boards last.
Main Main Cabin
Standard economy with advance seat selection, full SkyMiles earning, complimentary snacks and drinks, and no change fees on most U.S. tickets.
Comfort Delta Comfort
Extra legroom, dedicated overhead bin space, earlier boarding, and upgraded snacks and drinks. This was previously called Comfort+.
Premium Delta Premium Select
International premium economy with a wider seat, more recline, upgraded meals, and earlier boarding.
First Delta First
Domestic first class with recliner seats, priority boarding, and a full meal on longer flights.
One Delta One
The long-haul international business cabin with fully lie-flat seats and Sky Club access, plus Delta One Suites on many widebody jets.
Wi-Fi and entertainment
Wi-Fi is free on most of Delta's mainline fleet for SkyMiles members, and joining SkyMiles costs nothing. Most aircraft have seatback screens with movies, TV, and live channels, and you can also stream to your own device through the Fly Delta app. Complimentary snacks and drinks come with Main Cabin and up.
Check-in and boarding
Check-in opens 24 hours before departure in the Fly Delta app, on delta.com, at a kiosk, or at the counter. Delta's 45-minute rule sets the domestic cutoff: if you're checking a bag, drop it at least 45 minutes before departure, or be checked in 30 minutes before if you aren't, and everyone needs to be at the gate 15 minutes prior. Some airports, like New York JFK, want 60 minutes. Boarding goes by zone, with Delta One, First, Premium Select, Delta Comfort, and Sky Priority ahead of Main Cabin and Basic Economy last. Pre-boarding is offered to customers who need extra time or assistance and to active military, and Delta suggests arriving about two hours before a domestic flight.
Delta destinations and routes
Delta's network covers the U.S. and reaches Europe, Latin America, Asia, and beyond. You'll find Delta international flights to the major European capitals, including popular runs to Barcelona, plus sun routes across Mexico and year-round service to Puerto Rico. Domestically it's strong out of New York, Boston, and Seattle, and right across California. Most long trips connect through a hub like Atlanta, Detroit, Minneapolis, or Salt Lake City.

Atlanta to Dallas
JFK → LAX New York to Los Angeles

Booking, fares, and managing your trip
Book a Delta flight and you can pull it back up anytime under My Trips to check flight status, change a seat, or add a bag. Delta's low fare calendar shows the cheapest days across a month at a glance, and Delta Vacations bundles flights with hotels and cars. A few ways to pay less:
Delta's fares are usually lowest on Tuesdays, Wednesdays, and Saturdays and highest on Fridays and Sundays, so shifting a day or two can cut the cost.
Sign up for Delta's fare alerts and keep an eye on Travel Tuesday and flash sales, when Delta discounts cash fares and award seats for a short window. You can also check our deals page for current Delta offers.
Compare nearby airports and use the low fare calendar's flexible dates; a round-trip usually prices lower than two one-ways.
Delta Main Basic earns no miles and can't be changed, so standard Main Cabin is often the better value once you weigh that up.
